Zusammenfassung: | Recently, pre-mixed lean combustion has gained the attention of many researchers, who are investigating compression ignition characteristics of this type of mixture. Previous research in our laboratory has shown that low NOx combustion can be obtained by PREDIC (PREmixed lean DIesel Combustion). While NOx emissions were very good, the fuel consumption was greater than that of a conventional engine, due to a lack of ignition timing control. So in this study, ignition timing control was attempted using two fuels. Results showed that ignition timing control was possible using a low cetane fuel (such as methanol or α-methyl naphthalene) after the diesel fuel main injection. The injection timing and quantity of methanol affected the ignition timing of PREDIC. |
